RECEPTACLE.

Patented Feb. 1, 1921.

Application led March 25, 1920. Serial No. 368,523.

To all whom it may concern Be it known that I, STEPHEN DEMBowsKI, a citizen of the Republic of Poland, residing at Hamtramck, in the county of `Wayne and State of Michi an7 have invented certain new and useful m rovements in Receptacles in fhich Fluids Iay be Boiled, of which the following is a specilication.

My invention relates to an improvement in receptacles in which fluids may be boiled and particularly to means adapted for use in a pot or other cooking utensil to prevent the fluid carried therein from boiling over. It

is a simple device of easy adaptation to a conventional boiling pot or other utensil and inexpensive to manufacture.

In the drawings:

Figure l is a vertical section through a cooking utensil showing my improved device in lace. y

ig. 2 is a plan view.

Fi 3 is a fragmentary cross section show! ing t e tilting action of the disk.

Let a. representa receptacle or pot for containing fluid provided with a handle 7). The bottom of the pot or receptacle is indicated as c. A stud, shown in the drawing as a threaded stud adapted to receive a nut is indicated as d. This stud is hereshown as integrallwith the bottom cl It is apparent that. it might be attached in a number of ways. It might be a bolt passing through the bottom of the pot `iii-the jointure was made water tight. This is merely shown as a preferred form of construction.

A circular member e `concaved on its lower side is provided with a central passageway therethrough of slightly larger diameter than thediameter of the stud d, and adapted to be received over said stud and held thereon by means of a nut f; This member e is adapted to rest on the bottom of the receptacle and the passageway through which the stud passes is of such size as to permit of the tilting movement of the disk as shown in Fig. 3. It will further be observed that t-he diameter of member e is such that it does not completely cover the bottom of the rehas receded sufficiently and suiicient gas bubbles have gathered the member e will tilt as shown in Fig. 3 and the gas bubbles will escape therefrom underneath the side and the water will again rise and occupy the space vacated by the gas, and the process will be repeated again. In Fig. lthe boiling operation has just begun, the pan member e is slightly elevated from the bottom of the pot. In Fig. 3, the water has receded underneath member c by reason of the collection of the gas bubbles to such an extent as to cause such member to tilt1 as shown, allowing the escape of the gas, as shown, at one side thereof.

This vessel can be easily cleaned. The member e occupies but a small amount of space. It will add but little to the cost of the finished article, and it will prevent the boiling over of the fluid. even though the vessel is left unattended. y

`Having thus described my invention what I claim is:

l. In a device of a class described, a cook ing utensil for containing fluid, an upwardly projecting stud carried axially of the bottom of such utensil, a disk, concaved on the lower side, sleevedover such stud in such a manner that the same may be tilted thereon and so as to normally rest on the bottom of the uten- PATENT OFFICE.

lower side loosely Vsleeved over said stud, means for retaining such disk in place on said stud yet so loosely as to permit of a slight uplifting of the disk from the bottom of the ,receptacle and topermit of aitilting Vmovement of the disk.

3. In a device of the class vdescribed the combination (of. a receptacle, a device concaved on its lower side, said device normally resting on the bottom of the receptacle, and 10 means for limiting the upward movement of said device but ermittilw it t0 tilt.
